Mr. Baldwin
Is one astute Dude!! The first part is His intelligence, the second is My addition..
What you miss is that your "world saving" batteries DON'T get built without a LOT of energy...that energy is mostly oil. You may save some oil driving the car...but you used just about all...if not all or more...oil making the car...because batteries need a lot of energy to create. Lithium is in limited supply you're NOT going to turn ALL the vehicles into electric. The point You fail to make is what to do with a few million pounds of Toxic Waste, Spent/worthless batteries? None last forever?? A suggestion, Load them up on elons rocket ships and destroy the universe at the same time as Earth.. |

You are absolutely correct...they don't last forever...they'll need recycling...which TAKES ENERGY. MORE energy than those batteries will produce. It's called entropy...most people don't know what it is...and fail to account for it. There is NO "perpetual motion" You CAN'T get MORE energy OUT of a battery than you put in. No matter how efficient a battery is...diesel will beat it out. Pound for pound, dollar for dollar. As the cost of oil goes up...so will the cost of manufacturing batteries. It's a zero sum reality. EREI - energy return on energy invested. The REAL solution..the ONLY solution that works...that IS sustainable...isn't going to be popular. The planet has twice as many people as it can carry indefinitely. The current population "runs out of supplies" in the not too distant future. And medicine is trying to PROLONG lives? The POOR included? We used to have wars and disease that would cull half the worlds population here and there. And that was BEFORE oil. A planet with a billion would...even 2 billion. But NOT 9 billion +. Living to be well over 100? It's a zero sum world out there...there's NOT enough to go around. Right now...we pump oil as fast as we can...THE REAL REASON FOR FINDING ALTERNATIVE ENERGY SOURCES...they WANT us to cut back...they NEED us to cut back because the population keeps growing ...there is always more demand...and it can't be pumped out any faster. We already pumped out ALL the easy oil. NOW...we MUST pump in the arctic, out in frigid oceans, through 6 miles of water, we MUST frack the OLD wells because the other sources aren't putting out fast enough...to meet the increasing demand. Oil is used for EVERYTHING. It's the key to modern western civilization. We've reached...peak pumping...not peak oil. The oil is there...but it's thick...like molasses...you can only get it out so fast. |

Nol dougie...it is YOU who doesn't understand. I used entropy to TRY to explain to the ignorant rabble that it takes ENERGY to "organize" to "build" something. There's a LOT more energy going into batteries than JUST mining the f@cking lithium! There's a LOT more energy going into MAKING battering...than you'll EVER get out of them. Right now...energy is cheap...oil, gas...it's cheap. What does it cost...$3 dollars a DAY to electrify your house? Heat, air, reefer, TV, computer, lights, hot water...all for $4 a day. WHAT would it cost you if you had to do it EXCLUSIVELY with batteries? How much dougie? Batteries ARE f@cking "physical chemistry" you stupid f@cking idiot. What...are you black? A woman using a man's name? You DO NOT get more energy out of a battery than it took to MAKE and CHARGE the f@cking battery you retard. You think you're going to f@cking replace oil with batteries? Thermodynamics...Newton...how quaint. Go back to the kids table until you grow up a little more...you're not ready for the adult table and adult conversations yet dougie. You ARE being duped. |
Here ya go douchie...oops...dougie.
"entropy The idea of entropy comes from a principle of thermodynamics dealing with energy. It usually refers to the idea that everything in the universe eventually moves from order to disorder, and entropy is the measurement of that change. The word entropy finds its roots in the Greek entropia, which means "a turning toward" or "transformation." The word was used to describe the measurement of disorder by the German physicist Rudolph Clausius and appeared in English in 1868. A common example of entropy is that of ice melting in water. The resulting change from formed to free, from ordered to disordered increases the entropy." |

It took more energy (created more heat) to make and run your air conditioner than the amount of energy (heat) it removes. Likewise...it takes MORE energy to manufacture AND charge a battery than you'll EVER get out of it. They talk about efficiencies in batteries how efficient they are at taking the energy you input and turning it into chemical energy to be released later. NOTHING is FREE...you NEVER end up with more than you started with when it comes to energy. If you don't understand now...well...you may never. According to you...you could run EVERYTHING on the batteries you are manufacturing with NO outside energy...which is false. This is the minutiae that most people miss. Sorry...didn't mean to curse at you...it's not your fault. |

The ONLY reason you CAN think this way...so nonchalantly about "energy" and "work" is that oil and gas are basically free. ONLY with oil/gas do you get back 100X the energy you put into getting and using it. "A barrel of oil contains about six gigajoules of energy. That’s six billion joules or 1667 kilowatt-hours. No, we don’t have any idea how much that is, either, so let’s think about the equivalent. Sit a reasonably healthy male adult – let’s call him Jim – on an exercise bike wired to an efficient generator, and he can produce 100 watts for you. So after Jim has pedaled an hour he’s produced 100 watt hours of energy, or 1/10 of a kw-hour. To produce the same energy as that in a gallon of gasoline, 33 kilowatt-hours, Jim would need to pedal 33 X 10 = 330 hours. We need to be legal, of course, so Jim only pedals 40 hours per week. Jim’s desperate, so let’s assume he agrees to take no breaks and never stops working to chat at the water cooler or to check in with his friends on Facebook. He pedals straight through for 40 hours per week. He will have pedaled enough to equal the energy in a gallon of gasoline in a little more than eight weeks. Because Jim’s desperate, he gladly works for minimum wage, so your energy equivalent of a gallon of gasoline is a bargain at $6.55 X 330 = $2,194. How’s the price of gasoline lookin’? Jim likes working for you, so let’s ask him to pedal long enough to produce the same energy as that in a barrel of oil, 1667 kw-hours. Easy to figure. 1667 divided by 1/10, or to say it another way, 1,667 X 10, or 16,667 hours of pedaling. That’s 417 weeks. Jim must love pedaling that bike, because he never takes a vacation. Jim will have pedaled enough to produce the energy in a barrel of oil in 417 divided by 52 = 8.01 years. Congress has cooperated with you during this entire adventure and kept the minimum wage stable at $6.55 per hour, so your energy equivalent from Jim will cost you only $6.55 X 16,667 = $109,169." "If this is true, oil is essentially “free” energy at the current price. I decided to check it out, as the claim seemed a little hard to believe at first. After some quick calculations from first principals (see below), I found that for a purely theoretical task, like heating water with a pedal powered generator, the claim is correct. It would indeed take 12 years of laboring to produce the same amount of heat energy as a single barrel of oil." You CANNOT simply "replace" oil with ANYTHING short of a "Mr Fusion" from Back to the Future. |

You said batteries can take over for oil...can replace fuel. I said they can't. So...prove it. Get me the TOTAL cost...in ENERGY...to build a battery...energy used charging it...and compare that to it's total energy output over it's life. It won't be CLOSE to the amount of energy used to create it. It's energy negative...there is negative EREI (energy return for energy invested). It takes more energy to make your battery than it will ever produce. So WHY "switch"? You're going to use more energy than you gain. A barrel of oil contains the equivalent of 8 "man years" of "energy", of "work". One man working continuously, no breaks, no days off, 24/7, for 8 years in ONE barrel of oil. How much is in your battery? REMEMBER...EVERY CHARGE has energy costs. You say: "I can use the sun to charge the battery...it's free...solar is free". Au contraire...you MUST factor in the ENERGY COST of your solar charger. The sun's energy is HARDLY free. Solar panels take a lot of energy to mine, refine, manufacture, the electronics need fabrication plants. Copper needs mining, can't use plastic for anything...it's made of oil. A barrel of oil is $60...a barrel of diesel is $125. How much are your batteries? Batteries are NOT going to REPLACE fuels. Oh...another thing...the power grid. It can't handle adding 250 million electric cars. You DO know WHY they want us to conserve electricity? Why everything is "Energy star"? Because there's NOT ENOUGH to go around during peak demands. How do you handle road trips? Everyone can't charge at night. |

The suns power is locked up in oil. The sun and earth ALREADY DID THE WORK of putting the energy there. We just pump it out and use it...it's basically FREE energy. It's like a never ending "battery"...portable power...basically free. Creating a battery to supply the SAME amount of energy as that barrel of oil takes a WHOLE LOT OF ENERGY because WE are putting the energy into the BATTERY. And we MUST put in MORE than we get out. The reason I used entropy was to try to explain that once it's used it's gone...the barrel of oil OR the battery charge. Getting "another charge" of energy is as simple as pumping it out of the ground for oil...but for the battery WE must put that power back in and it is therefore LESS efficient to run vehicles on batteries than fuel. |

"Our analysis of the finances of Tesla’s Powerwall battery found that the payback period for purchasing Powerwall would be 38 years with on-peak rates at $0.15 per kilowatt hour and off-peak rates at $0.06 per kilowatt hour" You'd have to save more than $100 a month on electricity costs to pay for itself in the thirteen years it takes before you have to buy new batteries. The sun just doesn't put out enough energy to replace oil. To SUPPLEMENT it...YES. But not replace it. Oil ALLOWED modern western civilization. We will continue to be dependent on it until a NEW "free" energy source is developed. A "Mr Fusion". The whole CO2 thing is a hoax. They want us to conserve energy because we're at the limits of PROVIDING it in the amounts that a developing world requires. America is being brought down so the developing countries CAN develop. China uses more energy than America. The limits to growth are limits to available energy. Once all the fields are fracked...what do we do then? DO we NEED to cut back on our use of oil...of course...we don't disagree there. At this rate it's NOT going to last forever. What we MUST do...is cut the worlds population back to sustainable levels. We MUST cut it by at least half. |
Let ME try again...
Oil has a positive EREI...a battery is negative. You GET MORE energy from a barrel of oil than you use to get it...a batter consumes MORE energy than it can supply. "Energy returned on energy invested: In physics, energy economics, and ecological energetics, energy returned on energy invested; or energy return on investment, is the ratio of the amount of usable energy delivered from a particular energy resource to the amount of exergy used to obtain that energy resource. It is a distinct measure from energy efficiency as it does not measure the primary energy inputs to the system, only usable energy. "When the EROEI of a resource is less than or equal to one, that energy source becomes a net "energy sink", and can no longer be used as a source of energy, but depending on the system might be useful for energy storage (for example a battery)." "To be considered viable as a prominent fuel or energy source a fuel or energy must have an EROEI ratio of at least 3:1" "For example, given a process with an EROEI of 5, expending 1 unit of energy yields a net energy gain of 4 units. The break-even point happens with an EROEI of 1 or a net energy gain of 0." "A 2015 review in Renewable and Sustainable Energy Reviews assessed the energy payback time and EROI of solar photovoltaics. In this study, which uses an insolation of 1700/kWh/m²/yr and a system lifetime of 30 years, mean harmonized EROIs between 8.7 and 34.2 were found. Mean harmonized energy payback time varied from 1.0 to 4.1 years." "In regard to fossil fuels, when oil was originally discovered, it took on average one barrel of oil to find, extract, and process about 100 barrels of oil. The ratio, for discovery of fossil fuels in the United States, has declined steadily over the last century from about 1000:1 in 1919 to only 5:1 in the 2010s" "ESOEI (or ESOIe) is used when EROEI is below 1. "ESOIe is the ratio of electrical energy stored over the lifetime of a storage device to the amount of embodied electrical energy required to build the device." "How deep should the probing in the supply chain of the tools being used to generate energy go? For example, if steel is being used to drill for oil or construct a nuclear power plant, should the energy input of the steel be taken into account, should the energy input into building the factory being used to construct the steel be taken into account and amortized? Should the energy input of the roads which are used to ferry the goods be taken into account? What about the energy used to cook the steelworker's breakfasts? These are complex questions evading simple answers.[37] A full accounting would require considerations of opportunity costs and comparing total energy expenditures in the presence and absence of this economic activity." These are ALL NEGATIVE...meaning they require MORE energy than they output. "Storage Technology ESOEI Zinc bromide battery 9 Vanadium redox battery 10 Pumped hydroelectric storage 704 NaS battery 20 Lithium ion battery 32 Lead acid battery 5 Compressed air energy storage 792" |

"all based on price" but NOT EROEI. HOW did we get BACK to this??? We were talking about BATTERIES...YOU claim that batteries are more energy efficient than fuel. PROVE THAT CLAIM...not "in the future"...not "maybe some day". You said batteries WILL replace fuels because they're more energy efficient. Show me. If you can't/won't talk about batteries and their energy cost vs energy output...we have nothing else to say...you keep dragging me out onto tangents that have nothing to do with your claim. Yes...Australia has solar and batteries out in the bush where electric hookups are prohibitive...now...WHAT does that have to do with batteries being more energy efficient than fuels in cars? Get a handle on the ADD...and focus. Get the EROEI for a battery and oil...compare them...oil wins...batteries...ALL batteries...lose...because they can NEVER be as efficient as oil...because they MUST BE MANUFACTURED and oil flows out of the ground. A barrel of oil is a barrel of free energy...a battery MUST be manufactured USING energy and MUST then be FILLED with MORE energy than it will be able to deliver. Can't you see that? They're pushing us towards alternative energy NOT because it'll EVER replace the energy of fossil fuels...but because WE'RE RUNNING OUT OF READILY PUMP-ABLE OIL. we must SAVE...hold onto...our precious oil. It's too valuable to burn up. Almost EVERYTHING is made with oil. Plastics, chemicals... I'm done doug...if you don't see it now...you won't with me explaining it. It's a con to steal your money...steal your labor...it's what they do. Working Americans work until May 24th to pay the government. We've given them $20 trillion so far...what have we gotten for it? America has dropped from # 1 to #25. MOST "crises" aren't really...they're just sold as one to get the IGNORANT public behind it. The earth IS warming...IF you believe the numbers...(ask people in ND right now if there's global warming)...but it's NOT CO2 doing it. CO2 contributes less than 1% to the greenhouse effect. That's science I DO know too. |
One more...
A barrel of oil has 1667 kilowatt-hours of power My last electric bill was 555 kilowatt-hour My entire house can run for 3 months on the energy from ONE barrel of oil. That cost me $60. How much would the batteries cost that could run my house 24/7 for 3 months? What would be the ENERGY cost to "charge them up"? MORE than they discharged because batteries are NOT 100% efficient. Better? |

PRICE has NOTHING to do with it...we're not talking about price...we're talking about ENERGY. Efficiency has everything to do with it...you claimed a battery can replace fuel. It will be as/more efficient. Tell me HOW MUCH ENERGY goes into making/charging a battery and how much energy is used to deliver a gallon of gas. For the gas...it's 1/5th...20% of the energy contained in that gallon of gas was expended refining and delivering that gallon of gas. For a lithium battery it's MINUS 32. 32X the energy contained in the battery is used to build/charge it. And EVERY time you recharge it...you go MORE negative because NO battery is 100% efficient. It IS all about efficiency. Until we can build a battery that recharges itself with water and air...a battery CAN'T be more efficient. |

No...YOU care what it costs in DOLLARS...I'm talking about ENERGY cost...HOW MUCH ENERGY DID IT TAKE TO MAKE THE BATTERIES...your battery car costs/requires multiples MORE in ENERGY costs (energy USED) to manufacture and keep charged. If "gas" goes up to $5 a gallon...the dollar COST of your batteries WILL go up too, the dollar COST of charging them WILL go up too. It IS a "zero sum" equation.

If you buy a battery for your flashlight the cost of all of the energy to make that battery is included in the purchase price. It has to be less than the purchase price or the battery company would lose money on every battery and they soon would be out of business. Everready batteries have been around for a long time. Flashlight battery or battery for an electric car the economics are the same. Next year I am going to buy a Chevy Bolt, an all electric car. Purchase price (without subsidies) is 38K. It will save me 10k in gasoline costs over its lifetime. If I compare it to gas cars costing 28k they come out ahead, more room and no limit on range but not by much. In today's prices the EV is almost price competitive. Why am I doing it, I want to say the the Koch brothers,Saudis, Iranians and Russians try being poor for awhile. If my economic analysis of buying an EV tomorrow is wrong please show me the error. Please don't try to baffle with scientific bull**** you don't understand. |

BUT...the point you don't get is...energy IS cheap because it's "fossil" fuels...energy sitting in the ground...waiting to be lit. It only costs $3 a gallon because speculators decided it was worth $3 a gallon...it's also $3 a gallon because there are 9 billion people ALL wanting some of it. Oil COULD be 30 cents a gallon. But your batteries...they MUST be built...from scratch...EVERYTHING going into you battery NEEDS energy to be made. And THEN it needs MORE energy to charge...more than you'll EVER get out. STOP thinking in terms of dollars...START thinking in terms of energy consumed and energy output. A barrel of oil RELEASES 5X more energy than is required to "make" that barrel. A Lithium battery CONSUMES 32X MORE energy to manufacture and charge than is will release during use. The MORE times you use your battery the WORSE the costs become because each recharge uses more energy than the battery can release. Your batteries are ONLY possible because there is almost unlimited CHEAP fossil fuels to create the energy required to create the battery. You are talking "dollars", I'm talking about actual "energy" Oil is a better "value" in energy terms. Dollar values are arbitrary and capricious. Dollar values change...energy requirements/output are fairly fixed. |

"Dollar values change...energy requirements/output are fairly fixed." You have a problem with that? You can go down to the La Brea tar pits and find the FREE energy USED to build things...like your batteries. I could heat a house for decades...I could use it for steam power...there are ALL kinds of uses for that oil...just sitting there...waiting to be scooped out. Where's your battery? We have to wait for the lithium to be mined and processed into metal...VERY energy costly. Then other items need to be manufactured...again ENERGY costly. It all has to be put together in a factory somewhere...more ENERGY. My barrel of oil cost me the energy to fill a barrel...100 calories? I will get 8 man years of energy...of work...from it. Is your battery ready yet? How much energy have you spent so far? You WILL get 32X LESS energy OUT of a lithium battery than you put in. BECAUSE: "energy requirements/output are fairly fixed" ALL batteries are energy SINKS...they consume FAR more...32X more...energy than they create. That energy comes from fossil fuels. NO "alternative energy source" is "self sufficient". Only oil is self sufficient because it's "saved sun energy". Meaning it can CREATE more energy than was used to get the outputted energy. More energy goes into a nuclear plant, a solar plant, wind farm than will EVER come out of it. It's a scam. Oil is 8 man years in a barrel. Solar, wind, and BATTERIES...ALL...require MUCH more energy to build than they'll ever produce. We CAN build them ONLY because we have OIL to provide the vast energy needed. It takes 32 barrels of oil to make a lithium battery that outputs the energy in ONE barrel of oil. Take away oil and you take away modern western civilization. |

"Germany is the fifth-largest consumer of oil in the world. Russia, Norway, and the United Kingdom are the largest exporters of oil to Germany, in that order.[38] Germany is the third-largest consumer of natural gas in the world,[citation needed] and imports gas from Russia via the Nord Stream; in 2016, Germany imported 49.8 billion cubic metres (bcm) of gas from Gazprom.[39] A terminal in Emden opened for gas from Norway in 2016.[40] Germany imports more than half of its energy.[41] Because of its rich coal deposits it has a long tradition of fuelling its economy with coal. It still is the fourth-largest consumer of coal in the world, even though domestic coal mining has been almost completely phased out, because German coal is a lot more expensive to mine than coal in China or Australia. Germany has the largest national market of electricity in Europe." "The main source of electricity is coal.[5] The 2007 plan to build 26 new coal plants[6] is controversial in light of Germany's commitment to curbing emissions." They can have "renewables" at 35% because they BUY 2/3rds of their energy from other countries. Germany CANNOT sustain itself with regard to energy...they HAVE to buy 2/3rd of what they use. HOW in the world can you use Germany as an example of a "successful" "renewable" energy country? They're 2/3rds short and must purchase energy from outside. It's as far fetched as comparing Costa Rica to the US. |

I usually know what I'm talking about. Doug...it IS physics...oil is concentrated energy from the sun accumulated over hundreds of millions of years...(unless you subscribe to the abiotic oil theories)...we can just pump it out and use it...as is. A battery must be manufactured and then it must be charged. As I said earlier...it takes 32 times more energy to MAKE a battery then you'll get out of it. It takes 32 barrels worth of energy to get out 1 barrel of energy from the battery. You are concerned with PRICE of energy which is an artificial descriptor of "cost". Whereas I was talking about the amount of energy actually used to make the battery. For a barrel of oil EQUIVALENT in energy...it takes 20% of that barrel to get 1 barrel of oil. For a barrel of oil EQUIVALENT in energy...it takes 32 barrels of oil equivalent of energy...to make and charge your battery. It takes 160X more energy to make a battery than it does to pump out a barrel of oil. The PRICE paid in dollars has little to do with the ENERGY costs because NOW...using fossil fuels...energy is ALMOST FREE in dollars. It's like water...it's almost free...leave your sprinklers on all night and it'll cost you less than $10. I've got it! WATER! Fossil fuels are like water...we pump it out of the ground and it's cheap. Your batteries are like BOTTLING the water. It adds an extra step. Extra hassle. It takes MORE energy. You can't run a city ONLY on bottled water...bottled energy. A city needs open spigots. Monetary value...the cost in dollars changes, it's variable. The ENERGY cost of building batteries is enormous...160X the energy cost of pumping fossil fuels. |
